Justice, good description of the lock ...
My crane ( 41 Mag Ti ) loosens after firing 20 + rounds , a good cleaning tightens it a little,
but firing more rounds loosens it...I do not know if it is a problem unique to my gun,
or with light weight , heavy mags...I should send it back, ( some day ),
But I believe the lock is not a good design for heavier mags in a LW gun ( My opinion ).
As for life time warrenty, not important to me at 69 yrs..Quality is more important,
Normally I would reccomend a Ruger ( but, sadly it seems they are having some quality issues
also, along with S&W; )
I do like the gun, A great woods carry gun, but if it had a positive crane Lock it would be
a much better gun..
Please, I am not bashing, just stating my opinion,
